How to access Laravel Auth in Ratchet

Question

I found a post on Laravel.io on how to load Laravel sessions into Ratchet which is outdated and uses Laravel 5.4 so I've altered a few things to get this to work with Laravel 8.x

public function onOpen(ConnectionInterface $conn)
{
    // Attach connection
    $this->clients->attach($conn);

    // Create a new session handler for this client
    $session = (new SessionManager(App::getInstance()))->driver();

    // Get the cookies
    $cookiesRaw = $conn->httpRequest->getHeader('Cookie');
    $cookies = [];

    if(count($cookiesRaw)) {
        $cookies = Header::parse($cookiesRaw)[0]; // Array of cookies
    }

    // Get the laravel's one - todo: try catch
    $sessionId = Crypt::decrypt(urldecode($cookies[Config::get('session.cookie')]), false);

    var_dump($sessionId);

    // Set the session id to the session handler
    $session->setId($sessionId);

    // Bind the session handler to the client connection
    $conn->session = $session;

    var_dump($conn->session->getId());
}

I then altered the send message too because I am receiving unexpected results.

public function onMessage(ConnectionInterface $conn, MessageInterface $msg)
{
    $conn->session->start();
    $sessionId = $conn->session->getId();

    var_dump($sessionId);

    if(!is_null(($decoded = json_decode(base64_decode($msg), true))) && array_diff(['message'], array_keys($decoded)))
        return;

    var_dump($decoded['message']);

    return;
}

I test this with JS front-end like so:

class WebRTC
{
    socket;
    constants;
    timerId;

    constructor(protocol, fqdns, port) {
        this.constants = {
            protocol: protocol,
            fqdns: fqdns,
            port: port
        };

        this.listenChanges();
    }

    listenChanges() {
        this.socket = new WebSocket(`${this.constants.protocol}://${this.constants.fqdns}:${this.constants.port}`);

        this.socket.onmessage = e => {
            console.log(atob(e.data));
        };

        this.socket.onerror = () => {
            this.socket.close();
        };

        this.socket.onopen = () => {
            console.info('Connected to WebRTC Chat Server...');

            this.socket.send(btoa(JSON.stringify({
                message: '{{ session()->getId() }}' // Expected session
            })));

            clearInterval(this.timerId);

            this.socket.onclose = () => {
                this.timerId = setInterval(() => {
                    this.listenChanges();
                }, 1000);
            };
        };
    }
}

new WebRTC('ws', '127.0.0.1', '8080');

& When the connection opens, I sent the session()->getId() which is the expected session I need. However, my output in the CLI is:

onOpen() : $sessionId

string(81) "b0e41cf0d856bdfc8427e1fdde62d5a154519f9c|MLXa9H2BbnQmySt2hRB360UANxLGHyz6iRMxGcoG"

onOpen() : $conn->session->getId()

string(40) "qyaDOQjNFlbrbjvvKRE1m5sN0dsGqqAsoMfkeqyU"

onMessage(): $conn->session->getId()

string(40) "qyaDOQjNFlbrbjvvKRE1m5sN0dsGqqAsoMfkeqyU"

JS blade formatted actual session that is sent as a message

string(40) "MLXa9H2BbnQmySt2hRB360UANxLGHyz6iRMxGcoG"

Here, my expected onMessage() method receive the dependency injected $conn (ConnectionInterface) with the ->session->getId() of the actual session()->getId() so I can make Auth::user() work.

Any ideas on what I'm doing wrong? I tried the var_dump($conn->session->get(Auth::getName())); as the Laravel.Io says to do but it returns null on the var_dump and my user is logged in.

This should then give me access to use User::find() or Auth::user().
